Connecting two networks.

I am trying to connect two similar networks. I am not sure if this is possible or not.

My network has cable internet access through a Airport Extreme wireless router to a hub that connects to all of my devices (iMac, Xbox 360, TiVo, Win XP computer). The other network also connects to the internet through a cable modem and has a linksys wireless router. My iMac connects to my network through ethernet and the second network wirelessly.

I can connect to either network separately. I would like to be able to transfer files and print to the other network while simultaneously logged on my network and accessing the internet through my modem.

Is this possible? If so what do I need to do?

Thanks,
Scott

There can't be two dhcp servers running on one network so,..


If you use dhcp on both networks (creating one) from the AE and connect the hub and router via uplink or x/over cable there will be communication to all machines.
